Blackjack is a casino card game where players bet on whether they can beat the dealer by getting as close to 21 as possible without going over. It’s a hugely popular game in casinos across the world and has millions of players every year. Online blackjack is a version of the game that can be played in online casinos; allowing players to enjoy their favourite game from anywhere.

Online Blackjack Casino Bonuses And Promotions

Online blackjack casinos offer a variety of bonuses and promotions to persuade players to join their sites. These bonus offers provide extra value for those who claim them, allowing players to enjoy a greater range of blackjack games.

We’ve outlined the most common types of blackjack online casino bonuses below, so take a look to discover more about what you can claim.

  • Matched Deposit Bonuses - A matched deposit bonus matches a percentage of a player’s deposit with bonus funds, enhancing the player’s deposit. For example, if a player makes a £50 deposit with a 100% matched deposit bonus, they will receive an extra £50 in bonus funds, giving them £100 to play with.
  • No Deposit Bonuses - No deposit bonuses give players bonus funds without the need to make a real money deposit. These bonuses offer players a risk-free way to enjoy real money blackjack games. After creating and verifying their account, players will receive a small bonus that can be used on real money blackjack games.
  • Cashback Bonuses - A cashback bonus is a type of bonus that gives players money back on their deposit losses, giving players more value on their deposit. For example, a player who loses £100 after claiming a 20% cashback bonus will receive an additional £20 in real money.
  • Welcome Bonuses - A welcome bonus is a type of casino bonus offered to players who are creating an account at an online casino. These bonuses are often very generous, offering large matched deposit bonuses or generous no deposit bonuses.
  • Reload Bonuses - Reload bonuses are offered to players who have already made a real money deposit at an online casino. These bonuses commonly take the form of matched deposit bonuses, giving players additional funds on top of their deposit.

Wagering Requirements

Players are often afraid of wagering requirements as they represent the biggest challenge to winning real money from their bonus funds. In fact, even casinos tend to hide their wagering requirements in their terms and conditions; treating them as if they’re a taboo subject.

However, wagering requirements aren’t as scary as they seem; they’re actually quite simple to understand. These requirements outline how much you need to play through your bonus before you can withdraw your winnings. Casinos aren’t in the habit of giving away free money, so they require players to play with their bonus before it can be withdrawn.

For example, a £10 bonus with 20x wagering requirements simply means that a player must play £200 worth of casino games (£10 x 20) before they can withdraw any winnings. If you try to make a withdrawal before you’ve met the wagering requirements, you may end up forfeiting any bonus funds you have in your account.

Remember, you’re not forced to take any casino bonus, so if you don’t want to take your casino’s bonus, you don’t have to! 

How To Play Online Blackjack - Rules & Guides 

If you’re new to the world of online blackjack, you may be wondering what exactly this game is and how you can get started. Well, you’re in the right place! We’ll walk you step by step through how to play blackjack online for the first time and give you an overview of the rules of blackjack.

Step By Step Guide To Playing Blackjack Online

Blackjack is a card game where players try to beat the dealer by getting as close to 21 as possible without going over. Players make their bets at the start of the hand and are dealt two cards face-up. The dealer is dealt one card face-up, and players must decide whether to hit or stand.

If a player hits, they are given the next card on the top of the deck, but if they stand, they do not take any more cards. If a player hits and their hand totals more than 21, they’re considered to have busted, and they lose their bet. Once the player has made their action, it’s the dealer’s turn to act. The casino’s blackjack game rules outline the actions that the dealer must take during their turn.

Once all players have finished their turn, the value of the hands is compared against the dealer. If the player has the higher hand, they win the bet, but if the dealer has the higher hand, the player loses the bet.

If you want to join in the fun and try this game out for yourself, follow our instructions below.

  1. Choose an online casino offering online blackjack games. You can find a number of quality options right here on this page.
  2. Create an account by filling in the forms provided.
  3. Make a real money deposit.
  4. Find a blackjack game that you want to try and click on the game’s icon to begin.
  5. Check the minimum/maximum bet limits and choose your bet size.
  6. Make your bet, then click the Deal button to start the game.
  7. Decide whether to hit or stand based on the hand you’ve been dealt
  8. Wait for the results of the game to see if you’re a winner.

While brick-and-mortar casinos use physical cards to determine what happens, online casino blackjack games use random number generators to determine which cards are dealt. These RNGs are tested to ensure that they offer a satisfactory level of randomness, ensuring that the gameplay is as similar to real casino gameplay as possible.

Scoring And RTP In Blackjack Online

In blackjack, the aim of the game is to get as close to 21 as possible without going over. According to the blackjack rules, each card is assigned a number score which is combined to create your overall total. Picture cards such as jack, queen, and king are given a score of ten, numbered cards are scored at face value, and the ace can either be 1 or 11, depending on the situation.

For example, if a player is dealt a jack and a seven, their hand’s score will be 17. If the player takes another card and is dealt a 3, their score becomes 20.

In situations where a player is dealt an ace and a number card, their hand total can be one of two numbers, as the ace can act as 1 or 11. For example, if a player is dealt an ace and a 4, their total can either be 5 or 15. This is described as a “soft” hand. If a player hits and is dealt a card such as 10, the total becomes 15, as the player’s hand cannot be higher than 21.

Blackjack is a popular game amongst casino players due to its high RTP rate. It has one of the lowest house edges in the casino; when players are playing perfectly, the house edge is only 0.5%.

Popular Blackjack Variants

As blackjack is such a popular game, online casinos in UK have developed new variants of blackjack to drive traffic to their sites. There are a number of different blackjack variants, but we’re going to take a look at some of the most popular options below.

  • Blackjack Switch - Blackjack Switch is a modern take on the game where players are dealt two hands and have the option to switch the second card they’re dealt between the two hands. However, in this game, if the dealer makes 22, the hand is a push rather than a win for the player.
  • Blackjack Surrender - In this game, players have the option of surrendering their hand after the initial hands have been dealt at the cost of half of their bet. This is advantageous in positions that aren’t good for the player.
  • All Bets Blackjack - All Bets Blackjack offers a number of side bets that offer more action and higher potential rewards. These side bets include 21+3, Perfect Pairs, and more.
  • Premium Blackjack - Premium Blackjack gives players a more refined gaming experience by offering improved graphics, smooth gameplay, and higher betting limits.
  • Lucky Lucky Blackjack - Lucky Lucky Blackjack offers players a side bet on the total hand value for each round. This provides more action and keeps players invested in every hand. 

Playing Online Blackjack - Free Play And Real Money Options 

Now that you know how to play blackjack and have familiarised yourself with the most popular variants, it’s time to jump into the action! Before you do so, you need to decide whether you’re going to play for real money or play the free version.

Online casinos give players the option of playing for fun or for real money, so it all comes down to user preference. Below, we’ll take a look at the key differences between playing blackjack for fun and real money.

Playing Online Blackjack For Free

Playing online blackjack for free gives you the opportunity to learn the ropes in a risk-free environment. Playing for free means that there is no risk of losing any money, so you’re free to try out the game, experiment with different actions, and try out new strategies without any risk. However, when playing for free, you also have no chance of winning real money; you don’t get to keep any of your winnings, no matter how much they are!

We offer a number of free blackjack games that you can enjoy; simply go to our games page and select the game you’d like to play to get started. You can also enjoy free blackjack games at online casinos by selecting the demo option on the game page.

Playing Online Blackjack For Real Money

The other option players have is playing online blackjack for real money. While this does come with the risk of losing real money, it offers a level of excitement that cannot be matched by the free version. It also comes with the potential to win real money, and any winnings you have while playing at real money casinos can be withdrawn straight into your bank account!

If you want to play online blackjack for real money, you’ll need to create an online casino account by filling in the forms with your personal details. Once your account has been created, you’ll need to fund your account with a real money deposit. As soon as your deposit hits your account, you’re free to start enjoying real money blackjack games. 

Play Online Blackjack Like A Professional - Tips And Strategies 

If you decide to play online blackjack for real money, you’ll want to be able to play like a true pro to give yourself the best chance of winning. To give you a helping hand, our experts have provided some helpful tips and strategies that you can use in your real money blackjack games.

Our Top 3 Blackjack Tips

If you’re looking to maximise your potential returns when playing blackjack, our experts are here to help. They’ve outlined their top three blackjack tips for you to look over below, so take note if you want to play blackjack for real money.

  • Choose High RTP Games - One of the great things about blackjack is its low house edge and high RTP. While blackjack variants may offer fun gameplay differences, they may offer a lower RTP than traditional blackjack games.
  • Set A Budget And Stick To It - The best way to maximise any potential returns is to have a budget for online blackjack games and stick tightly to it. By creating a budget, you allow yourself room to ride out the variance that can come when playing this game.
  • Know When to Hit or Stand - Blackjack isn’t a complicated game and it’s easy to learn when you should hit and when you should stand. You’d be surprised how often players make basic mistakes when playing this game, so make sure you know it inside out before you play!

Online Blackjack Strategies

Some players use dedicated strategies in-game to try and maximise their returns while playing online blackjack. Our experts have covered the most commonly used blackjack strategy options below and have evaluated them for use in online blackjack.

  • Martingale - The martingale betting strategy is based on doubling the size of your bet every time you lose a hand. The theory is that as long as you keep doubling your bet, you will eventually win and can reset. However, online blackjack tables have maximum bet limits that prevent players from using the martingale strategy effectively.
  • Basic Strategy - Basic strategy is what you can commonly find on blackjack strategy cards at the casino. This outlines exactly when you should stand, hit, split, and double down. By playing this strategy perfectly, you can reduce the house edge to 0.5%.
  • Card Counting - Card counting is a strategy where players count the value of cards that have been dealt and use that information to infer the likely value of the cards left in the shoe. However, this does not work in online blackjack, as cards are determined by an RNG rather than physical cards. 

Analysing The Pros And Cons of Online Blackjack UK Games

While there are a number of positives that come with playing online blackjack games, there are some drawbacks to be aware of. We want our readers to be fully informed before making their decision, so make sure you read through our list of pros and cons before you start playing.

Blackjack Online Pros

  • Available From Anywhere - Online blackjack games can be played from anywhere as long as you have a compatible device and an internet connection. You can enjoy these games from home or while on the move, and you don’t have to be in a casino to do so!
  • Selection Of Variants - Online blackjack casino sites offer a variety of different blackjack variants that you can’t find at the casino, such as Switch Blackjack, Single Deck Blackjack, and other regional variants.
  • Wide Range Of Betting Limits - When playing blackjack at an online casino, you can choose from games with a wide range of betting limits, allowing both high rollers and budget players to enjoy what’s on offer.
  • Immersive Casino Experience - Live dealer blackjack games offer an immersive casino experience that brings the feel of live casinos without having to be there in person.
  • Access To Bonuses & Promotions - Playing at online blackjack UK casinos gives players access to valuable bonuses and promotions, such as matched deposit bonuses and no deposit bonuses.

Blackjack Online Cons

  • Potential For Increased Losses - As the speed of play is significantly greater in online blackjack, the potential for higher losses is also greater.
  • Lack Of Social Aspect - Many online blackjack games lack the social aspect that can be found in casino blackjack games, which may limit the enjoyment for some players. 

Mobile Blackjack 

Mobile CasinoMany online blackjack casinos provide mobile gaming platforms that allow players to enjoy online blackjack while on the move. There are two primary ways online casinos will offer mobile blackjack games; they can either offer a mobile-optimised website that can be accessed via a phone’s web browser, or they can offer a dedicated casino mobile app that can be downloaded and installed onto your mobile device.

Playing online blackjack from your mobile device is a very similar experience to playing on your PC, with a couple of small differences. You may find that not every blackjack game is available on mobile devices, as some online casino games do not have the technology to run on mobile phones. You will also find that the playing experience won’t be as optimised; the gameplay may not be as smooth and the size of the buttons may be proportionally larger than they are in the PC versions.  

Live Dealer Blackjack Casinos 

Live dealer blackjack games are a new variant of online blackjack that has been taking the world of online casinos by storm. Rather than using computer animations, these games use real dealers with real casino equipment. These games are live-streamed to casino players, allowing them to bet in real time.

Live blackjack casinos offer a more immersive casino experience than traditional blackjack games, as you’re transported into a real-life casino environment. These games also offer a level of transparency that you can’t find in traditional online blackjack games, as you can see the dealers shuffle and deal the cards at the start of every round.

Blackjack Casino Deposit And Withdrawal Options 

A vital part of any blackjack casino is its deposit and withdrawal options. You need to know that there will be a number of secure and convenient ways for you to fund your casino account and withdraw your winnings once you’re done.

The best blackjack casinos offer a choice of payment options, such as the ones you can find below.

  • Debit Cards - Debit cards such as Visa and Mastercard offer players a convenient way to make online casino deposits. They are widely available at a number of blackjack casinos, offer high maximum transaction limits, and are extremely secure.
  • E-Wallets - Online e-wallets such as Skrill, PayPal, and Neteller offer a fast, secure way to make online casino transactions. They offer some of the fastest withdrawal options and are very easy to use.
  • Prepaid Cards - Prepaid cards such as Paysafecard are one of the safest ways to make online casino deposits. This payment method allows you to make online casino deposits without a bank account, but they are rarely used for withdrawals.
  • Bank Transfer - Bank transfers allow people to make online casino deposits and withdrawals directly from their bank account. While this is a very secure payment method, the withdrawal times are often significantly longer than other payment methods.
  • Pay By Phone Bill - Some online casinos allow players to make a deposit via their phone bill. The value of these deposits is taken from the player’s phone credit or is added to their phone bill at the end of the month. 

How We Review Online Blackjack Casinos 

We employ a team of casino experts with years of experience in the online casino industry to thoroughly evaluate and review each blackjack casino we recommend to our readers. Our experts work from an approved list of criteria that highlights the areas that matter most to the average punter.

If you want to learn more about our review process, take a look at our criteria below.

  • Payment Options - Another important feature of online casino sites is the variety of secure payment options they have available. The more payment options offered by a casino, the more flexibility you have while managing your bankroll.
  • Bonuses & Promotions - Online blackjack bonuses give players added value when making deposits, allowing you to get better value for money. We compare the various types of online casino bonuses offered by different sites to give you the best bang for your buck.
  • Licensing - We only ever recommend online blackjack casinos that have been licensed by respected gambling authorities such as the UK Gambling Commission. This is to ensure that our readers are recommended safe, secure, and regulated places to enjoy their favourite blackjack games.
  • Mobile Gaming - One of the advantages of playing online blackjack is the ability to play from anywhere, so we evaluate the mobile gaming options offered by each blackjack casino. This includes playing from mobile-optimised websites and downloading and testing dedicated casino apps.
  • User Experience - An important part of any blackjack casino is the user experience; we look for casinos that offer bright, colourful sites that are both easy on the eye and easy to use. This ensures that our readers always have a positive experience when gambling online.  

Blackjack Casino Software Developers 

When choosing your next online blackjack game, we recommend that you look at the game’s software developer as part of your selection process. You can find a number of blackjack casino games made by some of the best software developers in the industry, ensuring that you’ll have a top-quality blackjack experience.

Below, we’ve listed our top three favourite blackjack software developers.

  • Evolution Gaming - Evolution Gaming was founded in Sweden in 2006 and has gone on to become arguably the world’s leading live casino game developer. They offer a wide variety of best-in-class blackjack online UK games at a number of different online casinos.
  • Microgaming - Microgaming was founded in the Isle Of Man in 1994 and has used its decades of experience to create a variety of quality blackjack games, including European Blackjack, Classic Blackjack, and Bonus Blackjack.
  • Play'n Go - Play’n Go started in Sweden in 2005 and has grown into an internationally renowned online game developer. They’ve made a selection of high-quality blackjack games that work seamlessly on mobile devices, such as Single Deck Blackjack, Multi-Hand Blackjack, and European Blackjack. 


You need to have a higher-scoring hand than the Dealer without going over 21. If it's a tie, then you'll receive your bet back. However, a Blackjack Hand will beat a regular 21-point hand.

The short answer is no. That's because the cards are shuffled after every round in Online Blackjack. In land-based casinos, the deck is shuffled after several hands have been played. Some gamblers believe they can gain an advantage by keeping a score of the number of high cards drawn, but such tactics are not possible in the online version.

Yes, players can win real money when playing online blackjack. Players who play at an online casino after making a real money deposit are free to withdraw any winnings they earn while playing online blackjack. 

Online blackjack games from licensed and regulated online casinos are legitimate. Sites that have licenses from gambling authorities such as the UKGC offer legitimate games that are completely fair and above board. 

Blackjack is primarily a game of luck, but there are elements of skill that can determine the amount a player can win or lose. A player who plays perfect strategy will always outperform a player who makes random decisions in the long run.
